$(1)$ Design an adder for adding $2$ floating point numbers $(x+Y)$ where each number has a mantissa and exponent.

Show the high level design; your design should account for the ADD and SHIFT operations.

For example ADD: $[10101101]\mathrm{.}2{?}^5+[00101110]*2^7$

$1-$ Equate the exponents in both numbers; reduce the exp of the $2$ nd number: $[10111000].2^5$

$2-$ Add the two numbers $($the binary numbers$)$; and use the modified exponent $(5).$
